On F-contractions for weak α-admissible mappings in metric-like spaces

Abstract

In the paper, we consider some fixed point results of F -contractions for triangular α-admissible and triangular weak α-admissible mappings in metric-like spaces. The results on F -contraction type mappings in the context of metric-like spaces are generalized, improved, unified, and enriched. We prove the main result but using only the property (F1) of the strictly increasing mapping F: (0,+∞)→ (-∞,+∞). Our approach gives a proper generalization of several results given in current literature.
